T0 aZZ whom, it may concern.-

Be it known that I, OLIVER G. KIPP, a citizen of the United States,residing at Madison, in the county of Dane and State of Wisconsin,

have invented certain new and useful Improvements in Lubricators, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to improvements in lubricators of the class inwhich a positive feed of the oil is attained and the quantity thusdelivered is under control, it relating more particularly toimprovements of the sort illustrated in the Patent No. 699,191, issuedto me May 6, 1902.

In the accompanying drawings, Figure 1 is a front elevation of myimproved lubricator. Fig. 2 is a side elevation. Fig. 3 is a view,partly in side elevation and partly in section, of the pump-cylinder andpiston. Fig. 4 is a horizontal section on the line a: a; of Fig. 3. Fig.5 is a view partly in elevation and partly in vertical section. Fig. 6is a horizontal section on the line y y, Fig. 5. Fig. 7is a view, partlyin side elevation and partly in vertical section, showing the pistonwhen the eccentric has'been rotated approximately one hundred and eightydegrees fromits position in Fig. 3. Fig. 8 is a horizontal section onthe line 2 .2, Fig. 6. Fig. 9 is an elevation of the driving device.Fig. 10 is a perspective of part of the piston.

The oil-reservoir 1 has an opening in its top closed by a cover 2. Fromthe upper end of this reservoir extend two brackets 3 3, which support ashaft 4. In the lower end of the reservoir is located an oil-outlet 5.To one end of the shaft is secured a ratchet-wheel 6, and to the otherend of the shaft is secured an eccentric 7 supporting a strap 8. Theeccentric is located diagonally to the lengthwise direction of theshaft.

To the strap 8 is pivoted a yoke 9. The yoke is secured to a rod 10,having a connection with a piston 11 by a universal joint.

I have devised a peculiar connection for the yoke 9 and theeccentric-strap. I join them by trunnions or hinges 30, fitting eyes 31at the ends of the yoke 9. The axis 32 of this hinge connection lies inthe horizontal plane of the axis of the shaft4 or in approximatelyhorizontal planes near it and vibrates in said planes around thevertical axis of the piston passing through the axis of shaft 4. This isin contradistinction from the method of hinging these parts togetherpreviously devised by me and illustrated in my aforesaid Patent In theearlier mechanism I hinged or pivoted the fork to the lower part of theeccentric-strap 8, there being a downward projection from the saideccentric-strap to receive the pivot. When thus pivoted, the pitman-rod10 was vibrated through a long are and had two swinging movements, outand in, imparted at each revolution of the shaft. Moreover, the verticalplay of the hinge-axis of the rod 10 was increased by this movement.

In the present construction the hinge-axls is raised and lowered onlyslightly, the distance being equal to the eccentricity of the eccentricless the loss, vertically, due to ts inclination. The connecting-rod 10remains approximately vertical at all times, and the power is applied tothe piston economically and on proper lines, there being an avoidance ofall side thrust or torsion. The movements are entirely uniform andsmoothly efl ected.

The piston has a lengthwise slot 13, located to one side of the centerof the piston. It will be observed by reference particularly to Figs. 4,6, 8, and 10 that this slot 13 is so disposed relative to the inlet-duct40 and the outlet-duct 41 in the cylinder 14 that it never communicateswith both ducts 40 and 41 at the same time, Fig. 6, both ducts beingmomentarily cut off from the slot in the piston before communication isestablished with either one. As is understood, the piston 11 by reasonof its construction and the fact that it has imparted to it oscillatorymovements acts not only as a piston, but also as a valve and thedisposition of the slot as described permits the lubricator to feedagainst a considerable pressure with no other valve arrangement than theoscillating piston 11.

A cylinder 14 is secured to one side of the oil-reservoir and has athreaded extension 15, to which is connected the piping 16, leading tothe parts to which oil is to be delivered. A stuffing-box 17 is locatedat the upper end of the cylinder.

Upon the shaft 4 is pivoted an arm 18, from which extend transverselytwo projections 19 and 20, approximately parallel to the shaft.

- 7 forth.

A screw 21 has a connection with the projection 20.

To the arm 18 is pivoted a lever 22, which is located between theprojections 19 and 20 of the arm 18. This lever has a series of holes23. A dog 24L has a pivotal connection with the arm 18 near its free endand engages the teeth of the ratchet-wheel 6. A rod 25 has a pivotalconnection with the lever 22 and passes through an opening in an arm 26on the dog 2 A coiled spring 27 surrounds the rod 25, one end pressingagainst the extension 26 and the other end against the eye of the rod atits point of connection with the lever. I

In the earlier construction I provided a friction-holder for the ratchetfeed-wheel. I have devised a superior arrangement of parts for lockingthe wheel, which is herein shown. The bracket 3 is extended upward toform the arm 3", and at its upper end it supports a positively-actingdog 6. After the thrustrod is moved and the lever 22 and through the dog2 L has caused the ratchet-wheel to advance the latter is positivelylocked against retraction by the devices at 6 3 What I claim is 1. In alubricator, the combination of an oil-reservoir, a cylinder having inletand outlet ports for the oil, a longitudinally reciprocating andoscillating piston having a passage-way for oil therethrough adapted tobe alternately brought into communication with said inlet and outletports, a driving-shaft, an eccentric rotating with the shaft and held atan inclination thereto, the eccentric-straps and a power-transmittingrod between the eccentric-straps and the piston and pivotally connectedto the eccentric-straps at an axis lying in a plane passing through theaxis of the driving-shaft approximately perpendicular to the piston,substantially as set 2. In a lubricator, the combination of anoil-reservoir, a cylinder having inlet and outlet ports for the oil, alongitudinally reciprocating and oscillating piston having a passagewaytherethrough for oil adapted to be brought into communicationalternately with said inlet and outlet ports, a rotating eccentricsupported in a plane oblique to its axis of rotation, the

eccentric-strap and a power-transmitting rod connected to the piston andpivotally con- I nected to the eccentric-straps on an axis in the planepassing through the axis of rotation of the eccentric, substantially asset forth.

3. In alubricator. the combination of an oilreservoir, a cylinder havinginlet and outlet ports for the oil, a longitudinally reciprocatingpiston having a passage-way for oil therethrough adapted to bealternately brought into communication with said inlet and outlet ports,a rotating eccentric held in planes inclined to the axis of itsrotation, a strap or loop engaging with said eccentric, and apowertransmitting rod connected to the piston and hinged to the strap onan axis intersecting the axis of rotation of the eccentric,substantially as set forth.

4:. In a lubricator, the combination of an oil-reservoir, a cylinderhaving inlet and outlet ports for the oil, a piston in the cylinderhaving a passage for the oil therethrough adapted to be alternatelybrought into communication with the inlet and outlet ports of thecylinder, a driving-shaft, an eccentric on the shaft inclined thereto, astrap surrounding the eccentric and within which the latter turns,provided with diametrically opposite pivots disposed in a horizontalplane that approximates the horizontal plane of the axis of the shaft,and a power-transmitting rod connected with the piston and also with thesaid pivots of the eccentric-strap, the piston being so disposed thatits longitudinal vertical axis passes through the longitudinal axis ofthe drivingshaft, substantially as set forth.

5. In a lubricator, a pump like device, having a cylinder with alubricant-chamber and with an inlet and an outlet duct, and alongitudinally reciprocating and oscillating piston in the cylinder, thepiston being provided with a lengthwise slot arranged to have constantcommunication with the lubricantchamber in the cylinder and tosuccessively communicate with the said inlet and outlet ducts, but whenoccupying a mid-position to be entirely cut off from them both,substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
